Abstract

A method, system and computer readable medium for generating a cognitive insight comprising: receiving training data, the training data being based upon interactions between a user and a cognitive learning and inference system; performing a hierarchical topic machine learning operation on the training data; generating a cognitive profile based upon the information generated by performing the hierarchical topic machine learning operation; and, generating a cognitive insight based upon the cognitive profile generated using the hierarchical topic machine learning operation.

First claim

What is claimed is:

1. A computer-implementable method for generating a cognitive insight comprising:
receiving training data, the training data being based upon interactions between a user and a cognitive learning and inference system;
performing a cognitive learning operation via the cognitive inference and learning system using the training data, the cognitive learning operation implementing a cognitive learning technique according to a cognitive learning framework, the cognitive learning framework comprising a plurality of cognitive learning styles and a plurality of cognitive learning categories, each of the plurality of cognitive learning styles comprising a generalized learning approach implemented by the cognitive inference and learning system to perform the cognitive learning operation, each of the plurality of cognitive learning categories referring to a source of information used by the cognitive inference and learning system when performing the cognitive learning operation, an individual cognitive learning technique being associated with a primary cognitive learning style and bounded by an associated primary cognitive learning category, the cognitive learning operation applying the cognitive learning technique via a machine learning operation to generate a cognitive learning result;
performing a hierarchical topic machine learning operation on the training data, the machine learning operation comprising the hierarchical topic machine learning operation, the hierarchical topic machine learning operation providing a domain topic abstraction taxonomy, the domain topic abstraction taxonomy providing a classification of the training data as well as principles underlying the classification, the domain topic abstraction taxonomy providing a hierarchical taxonomy; and,
generating a cognitive insight based upon the hierarchical topic machine learning operation.

2. The method of claim 1 , wherein:
the hierarchical topic machine learning operation discovers topics contained within a corpus contained within the training data.

3. The method of claim 1 , wherein:
the hierarchical topic machine learning operation determines a degree of abstraction associated with each of a plurality of topics contained within the training data.

4. The method of claim 3 , wherein:
each of the plurality of topics are hierarchically abstracted into a hierarchical topic model, where topics that have a higher degree of abstraction are associated with upper levels of the hierarchical topic model and topics that have a lesser degree of abstraction are associated with lower levels of the hierarchical topic model.

5. The method of claim 3 , wherein:
each of the plurality of topics comprise a plurality of associated attributes; and,
the associated attributes are used when determining a degree of abstraction associated with each topic.

6. The method of claim 5 , further comprising:
associating a topic associated with an upper level of the hierarchical topic model with a topic associated with a next lower level of the hierarchical topic model based upon at least one of the associated attribute of the topic associated with the upper level of the hierarchical topic model with the topic associated with the next lower level of the hierarchical topic model.

7. A system comprising:
a processor;
a data bus coupled to the processor; and
a non-transitory, computer-readable storage medium embodying computer program code, the non-transitory, computer-readable storage medium being coupled to the data bus, the computer program code interacting with a plurality of computer operations and comprising instructions executable by the processor and configured for:
receiving training data, the training data being based upon interactions between a user and a cognitive learning and inference system;
performing a cognitive learning operation via the cognitive inference and learning system using the training data, the cognitive learning operation implementing a cognitive learning technique according to a cognitive learning framework, the cognitive learning framework comprising a plurality of cognitive learning styles and a plurality of cognitive learning categories, each of the plurality of cognitive learning styles comprising a generalized learning approach implemented by the cognitive inference and learning system to perform the cognitive learning operation, each of the plurality of cognitive learning categories referring to a source of information used by the cognitive inference and learning system when performing the cognitive learning operation, an individual cognitive learning technique being associated with a primary cognitive learning style and bounded by an associated primary cognitive learning category, the cognitive learning operation applying the cognitive learning technique via a machine learning operation to generate a cognitive learning result;
performing a hierarchical topic machine learning operation on the training data, the machine learning operation comprising the hierarchical topic machine learning operation, the hierarchical topic machine learning operation providing a domain topic abstraction taxonomy, the domain topic abstraction taxonomy providing a classification of the training data as well as principles underlying the classification, the domain topic abstraction taxonomy providing a hierarchical taxonomy; and,
generating a cognitive insight based upon the hierarchical topic machine learning operation.

8. The system of claim 7 , wherein:
the hierarchical topic machine learning operation discovers topics contained within a corpus contained within the training data.

9. The system of claim 7 , wherein:
the hierarchical topic machine learning operation determines a degree of abstraction associated with each of a plurality of topics contained within the training data.

10. The system of claim 9 , wherein:
each of the plurality of topics are hierarchically abstracted into a hierarchical topic model, where topics that have a higher degree of abstraction are associated with upper levels of the hierarchical topic model and topics that have a lesser degree of abstraction are associated with lower levels of the hierarchical topic model.

11. The system of claim 9 , wherein:
each of the plurality of topics comprise a plurality of associated attributes; and,
the associated attributes are used when determining a degree of abstraction associated with each topic.

12. The system of claim 9 , wherein the instructions executable by the processor further comprise instructions for:
associating a topic associated with an upper level of the hierarchical topic model with a topic associated with a next lower level of the hierarchical topic model based upon at least one of the associated attribute of the topic associated with the upper level of the hierarchical topic model with the topic associated with the next lower level of the hierarchical topic model.

13. A non-transitory, computer-readable storage medium embodying computer program code, the computer program code comprising computer executable instructions configured for:
receiving training data, the training data being based upon interactions between a user and a cognitive learning and inference system;
performing a cognitive learning operation via the cognitive inference and learning system using the training data, the cognitive learning operation implementing a cognitive learning technique according to a cognitive learning framework, the cognitive learning framework comprising a plurality of cognitive learning styles and a plurality of cognitive learning categories, each of the plurality of cognitive learning styles comprising
